animals    plants     cells

plants

200

Do fungi consume their food or make their own food? 

Consume their food

300

All living organisms are related. What do all living organisms have?

They all have at least one cell. 

400

How do we know that modern boas were connected to the Titanoboa? 

Their skeletons were similar when compared.

500

How do scientists decide if a modern organism is related to an ancient one? 

They compare the fossils to find connections.

Genes

100

DNA strands create _______________, which gives the cells information about traits that the organism will have.

Chromosomes

200

A fish reproduces asexually. How much of its DNA will be passed to its offspring? 

100%

300

A fish reproduces sexually. How much of its DNA will be passed on to its offspring? 

50% because it needs DNA from both parents. 

400

How many chromosome pairs do humans have? 

23

500

This is where the DNA is stored in the cell. 

Nucleus

Punnett Squares

100

CAPITAL LETTERS represent ________________ traits. 

dominant

200

Lowercase letters represent _______________ traits.

recessive

300

If B represents dominant brown eye allele and b represents recessive blue eye allele, what would the genotype of a blue-eyed person be? 

bb

400

If a monster with dominant scaly skin (SS) crosses with a monster with recessive fur (ss), what is the likelihood that the offspring will have scaly skin? 

100%

500

If pea plants have a dominant color of purple (P) and a recessive color of white (p), then what would the phenotype of a flower with genotype Pp?

purple

Misc.

100

If an organism is multicellular, what does this mean?

The organism has many cells.

200

If an organism is unicellular, what does this mean? 

The organism is made of one cell. 

300

What does it mean if a genotype is homozygous? 

It means that the genotype has either two dominant genes or two recessive genes. 

400

What does it mean if a genotype is heterozygous? 

It means that the genotype has one dominant gene and one recessive gene. 

500

What is the difference between a genotype and a phenotype? 

The genotype is the actual genes an organism has. The phenotype is how those traits are expressed (what we see)
